. a is A Ul '(illbll-idl GEORGE W. IECK, JR, AND WILLARD IVL FAEROW, SE,OF WASHINGTON, DISTRICT OF COLUMBIA.

To all whom it may concern:

Be it known that we, GEORGE lV. PEOK, Jr., and WILLARD M. FAnnow, Sn,citizens of the United States of America, and resident-s of the city ofl/Vashington, in the District of Columbia,have invented certain new anduseful Improvements in Front Gun- Sights, of which the following is aspecification.

This invention relates to certain new and useful improvements in gunsights and pertains more particularly to the sight which is known as thefront sight and belongs to that class of front sights designated in theart as revolving sights, being so constructed and arranged as to berotated to bring a different size or shape of bead into line with thesight, for an obvious purpose.

The present invention has for its objects among others to provide animproved looking device for the revoluble sight, easily manipulated,simple in its construction, yet efiicient and reliable in its operation.

e aim further at improvements in the details of construction whereby thedevice is made capable of manufacture at minimum cost, easily appliedand not liable to become damaged or to get out of order.

We are aware that it has been proposed to provide a gun sight in thenature of a rotatable or revoluble holder carrying a plurality ofsights, with a spring disposed beneath the sight and bearing against aplurality of the sights which are not in operative position. WVe employa spring looking device embodying a pivot for the revoluble sight holderand a locking member continuous of said pivot for engagement with thesaid holder to hold it in any of its adjusted positions. The naturaltendency of the spring is to hold the holder locked, pressure upon thespring releasing the locking member and allowing the sight holder to berevolved into the desired position. The locking is automatic and thelocking member is so disposed as to enter a depression or cavity in theholder, so that the latter can not he accidentally revolved, notdepending upon the frictional contact of the spring with the sight-s.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be particularly pointed out in theappended claims.

The invention is clearly illustrated in the Specification of LettersPatent.

accompanying drawings, which, with the numerals of reference markedthereon, form a part of this specification, and in which- Figure 1 is aside elevation of a portion of a gun barrel equipped with our improvedform of sight. Fig. 2 is a top plan thereof. Fig. 3 is an end viewlooking in the direction of the arrow in. Fig. 1. Fig. 4 is alongitudinal section on the line 44 of Fig. 2. Fig. 5 is a verticalcross section on the line 55 of Fig. 1.

Like numerals of reference indicate like parts throughout the differentviews.

Referring to the drawings, 1 designates the gun barrel which, it will beunderstood,

may be either of the cylindrical or octag-' ona-l form, both beingcommon in the art, and the present invention as applicable to one as tothe other and hence not restricted in that regard. Disposed within adovetailed recess 2 in said barrel, which recess extends transversely ofthe length of the barrel, as is evident from the drawings, is a basemember 3 having the shoulders 4 upon opposite sides which bear againstthe outer wall of the barrel, and from which base rise the uprights 5within the space 6 between which is disposed the revoluble sight member7. This member, as seen best in Fig. 5, which constitutes the sightholder, has projecting therefrom a plurality of sights or beads, in thepresent instance three, although the number may be varied. These sights8, 9 and 10 are of different sizes and shapes, as seen clearly in Fig.5, any one of which may be brought into operative position and theresecurely fastened. In Figs. 1, 3 and 5, the sight or bead 8 is shown insuch operative position. In Fig. 4, the sight or bead 10 is shown insuch operative position.

The holder 7 is revolubly mounted in position between the uprights 5upon a pin 12 which passes through said uprights and through a hole 11centrally through said holder, as seen best in Fig. t. The one end ofthis member 12 is headed, as at 13, the head bearing against a platespring 14:, the ends of which are extended to bear against the oppositeends of one of the uprights 5, as seen at 15 in Fig. 2, so as to servein holding the spring against displacement. The opposite end of this pinis bent upon itself, as seen at 16, the terminal 17 thereof extendingsubstantially parallel with the main sition and there firmly held.

portion of the pin, this return member 17 being passed through anopening in the upright 5 opposite that adjacent the headed end of thepin and normally projects into an opening 18, 19 or 20 in the sightholder "7. In Fig. 5 this return member 17 is shownas engaged in theopening 18 in such sight holder. These openings 18, 19 and 20 aredisposed in radial alinement with the sights 8, 9 and 10, so that whenthe return member 17 is engaged in any .one of said openings, theselected sight will be in its operative po- The spring 1 1 serves tohold this return member in locked engagement, so that accidentalmovement of the sight holder is prevented.

Whenever it is desired to revolve the holder 7 so as to bring adifferent sight into operative position, all that it is necessary to dois to apply pressure' to the spring let in the direction of the arrow inFig. 4, when the pivot and the return member 17 are pushed inthedirection of such arrow and said return member is brought out ofengagement with the opening in the holder, when the latter is free to berevolved in eithei directionfto bring the required sight intooperativeposition. lVhen such selected sight is in proper position, ifpressure upon the spring is released, the said spring will force thereturn member into the appropriate opening and the holder is locked. Itis to be noted that the locking is positive, that suchhlocking is notdependent upon frictional "engagement merely of a spring with a memberof the sight holder and that accidental engagement of anything with thesight cannot move it from its proper posit-ion.

From the foregoing, it will be evident that we have devised a simple,cheap, yet efficient and reliable revoluble or changeable sight, andwhile the structural embodiment of the invention as herein disclosed iswhat we at the present time consider preferable, it is evident that thesame is subject to changes, variations and modifications in detail,proportion of parts, etc, without departing from the spirit of theinvention or sacrificing any of its advantages. e, therefore, do notwish to limit ourselves to such exact details, proportions of parts,etc, but reserve the right to make such changes, variations andmodifications as come properly within the scope'of the protectionprayed.

I Vhat is claimed as new is 1. In a gun sight, a revoluble sight holderprovided with a plurality of sights, a pivot for' said holder endwisemovable there through, a locking member integral with one end of saidpivot and adapted to extend endwise into the holder in a plane parallelwith the pivot, and a spring acting upon the other end of the pivot,said pivot and locking member being simultaneously movable endwise inthe same direction.

2. In a gun sight, a base, uprights rising therefrom, a revoluble sightholder disposed between said uprights, and a pivot pin passed throughsaid uprights and centrally through the holder and having one end bentupon itself and working through an opening in one of the'uprights andengageable with an opening in said holder.

3. In a gun sight, a base, uprights rising therefrom, a revoluble sightholder disposed between said uprights, a pivot pin passed through saiduprights and centrally through the holder and having one end bent uponitself and working through an opening in one of the uprights andengageable with an opening in said holder, and a spring acting upon theother end of said pivot for normally holding said bent end of the pivotin engagement with the holder to lock it against rotation.

4:. In a gun sight, a base, uprights rising therefrom, a sight holderdisposed between said uprights and having a plurality of sights and aplurality of corresponding openings, a pivot pin passed centrallythrough said holder and through the uprights and having one end bent andreturned upon itself to form a locking member, said locking membermovable through one of the uprights and into an opening in the holder,and a spring acting upon the other end of said pivot.

5. In a gun sight, a base, uprights rising therefrom, a sight holderdisposed between said uprights and having a plurality of sights and aplurality of corresponding openings, a pivot pin passed centrallythrough said holder and through the uprights and having one end bent andreturned upon itself to form a locking member, said locking membermovable through one of the uprights and into an opening in the holder,and a spring acting upon the other end of said pivot, said holder havinga plurality of openings disposed radially with reference to said sightsfor the reception of said locking member.
